Photoinduced processes in nanocrystals of cadmium selenide in an external electric field
Abstract
The dependence of photoinduced processes in cadmium selenide nanocrystals in an external electric field on the energy of the exciting photons is established. A relationship between the photoinduced buildup of photoluminescence and its quenching in an external electric field in quantum sized cadmium selenide nanocrystals is demonstrated. The mechanisms for the quenching of the photoluminescence and for the influence of the exciting photon energy on the photoinduced processes are discussed.
